Fluid-filled chamber for an article of footwear

ABSTRACT

A fluid-filled chamber is provided and includes a first barrier layer, a second barrier layer, a foam structure, and a tensile member. The second barrier layer is secured to the first barrier layer to define an interior void between the first barrier layer and the second barrier layer. The interior void contains a predetermined volume of fluid. The foam structure and the tensile member are disposed within the interior void, whereby the tensile member includes a plurality of fibers extending in a first direction between the first barrier layer and the second barrier layer.

TECHNICAL FIELD

The present disclosure relates generally to articles of footwear andmore specifically to a fluid-filled chamber for use with an article offootwear and a method for making a fluid-filled chamber.

BACKGROUND

This section provides background information related to the presentdisclosure and is not necessarily prior art.

Articles of footwear typically include a sole structure that provides alayer between the foot on which the article of footwear is worn and aground surface. The sole structure prevents the foot from contacting theground surface and provides a degree of cushioning to the foot duringuse. The sole structure typically includes an outsole that contacts theground surface and a midsole that supports, stabilizes, and cushions thefoot. A polymer foam material may form the midsole to provide a level ofcushioning that minimizes the forces felt by the foot when the outsolestrikes the ground surface.

While traditional midsole materials, such as polymer foam materials,provide a degree of comfort and stability, such polymer foam materialsare typically tailored to provide a specific type of cushioning and aregenerally limited in that regard. For example, stiffer foam materialsprovide a more responsive feel during use but are less capable ofabsorbing impacts. Conversely, softer materials are less responsive butprovide a greater degree of cushioning and are therefore better suitedthan stiffer materials for applications that favor impact absorptionover responsiveness. Accordingly, providing a sole structure with morethan one type of cushioning system provides an article of footwear withboth a responsive feel and the ability to absorb impacts during use.

In an effort to balance responsiveness and cushioning, footwearmanufacturers typically provide a sole structure with more than one typeof cushioning. For example, a midsole may be formed from a polymer foammaterial that is used in conjunction with rubber posts or resilientmembers. The posts provide a responsive feel during use while thepolymer foam provides cushioning. While rubber posts or other resilientmembers may be used in conjunction with polymer foam, other cushioningsystems such as fluid-filled bladders may alternatively be used inconjunction with polymer foam depending on the particular application.

While sole structures of conventional articles of footwear may includemore than one type of cushioning system, such systems are typicallyseparate and independent from one another. Accordingly, these systemsseparately provide the article of footwear with responsiveness andcushioning and only cooperate with one another once assembled into thesole structure.

Example configurations will now be described more fully with referenceto the accompanying drawings. Example configurations are provided sothat this disclosure will be thorough, and will fully convey the scopeof the disclosure to those of ordinary skill in the art. Specificdetails are set forth such as examples of specific components, devices,and methods, to provide a thorough understanding of configurations ofthe present disclosure. It will be apparent to those of ordinary skillin the art that specific details need not be employed, that exampleconfigurations may be embodied in many different forms, and that thespecific details and the example configurations should not be construedto limit the scope of the disclosure.

The terminology used herein is for the purpose of describing particularexemplary configurations only and is not intended to be limiting. Asused herein, the singular articles “a,” “an,” and “the” may be intendedto include the plural forms as well, unless the context clearlyindicates otherwise. The terms “comprises,” “comprising,” “including,”and “having,” are inclusive and therefore specify the presence offeatures, steps, operations, elements, and/or components, but do notpreclude the presence or addition of one or more other features, steps,operations, elements, components, and/or groups thereof. The methodsteps, processes, and operations described herein are not to beconstrued as necessarily requiring their performance in the particularorder discussed or illustrated, unless specifically identified as anorder of performance. Additional or alternative steps may be employed.

When an element or layer is referred to as being “on,” “engaged to,”“connected to,” “attached to,” or “coupled to” another element or layer,it may be directly on, engaged, connected, attached, or coupled to theother element or layer, or intervening elements or layers may bepresent. In contrast, when an element is referred to as being “directlyon,” “directly engaged to,” “directly connected to,” “directly attachedto,” or “directly coupled to” another element or layer, there may be nointervening elements or layers present. Other words used to describe therelationship between elements should be interpreted in a like fashion(e.g., “between” versus “directly between,” “adjacent” versus “directlyadjacent,” etc.). As used herein, the term “and/or” includes any and allcombinations of one or more of the associated listed items.

The terms first, second, third, etc. may be used herein to describevarious elements, components, regions, layers and/or sections. Theseelements, components, regions, layers and/or sections should not belimited by these terms. These terms may be only used to distinguish oneelement, component, region, layer or section from another region, layeror section. Terms such as “first,” “second,” and other numerical termsdo not imply a sequence or order unless clearly indicated by thecontext. Thus, a first element, component, region, layer or sectiondiscussed below could be termed a second element, component, region,layer or section without departing from the teachings of the exampleconfigurations.

Referring to FIGS. 1A-1B, an article of footwear 10 is provided and mayinclude an upper 20 and a sole structure 22. The sole structure 22 maybe attached to the upper 20 and positioned between the upper 20 and aground surface in a manner that prevents the upper 20 from contactingthe ground surface during normal use of the article of footwear 10.

The upper 20 and the sole structure 22 may extend from a heel end 12 toa forefoot end 14 along a Y-axis, and from a lateral side 16 to a medialside 18 along an X-axis. The heel end 12 may correspond with rearportions of a foot, including a calcaneus bone. The forefoot end 14 maycorrespond with toes and joints connecting metatarsal bones with phalanxbones of the foot. The lateral and medial sides 16, 18, respectively,may correspond with opposite sides of the footwear 10 extending from theheel end 12 to the forefoot end 14.

The upper 20 may include a body 26, a tongue 30, a fastening system 32,and a sockliner 34. Different materials may form the body 26 of theupper 20, including one or more of foam, textiles, leather, andsynthetic leather that connect together to form a shape of the upper 20.In this regard, the body 26 may be formed from one or more materialsthat are stitched or adhesively bonded together to form a footwearcavity 24 that receives and secures a foot for support on the solestructure 22. Suitable materials for the body 26 may include, but arenot limited to, textiles, foam, leather, and synthetic leather. Thematerials may be selected and located to impart properties ofdurability, air-permeability, wear-resistance, flexibility, and comfortto the foot while disposed within the footwear cavity 24.

The body 26 of the upper 20 may be formed to define a foot-receivingopening 28 in the heel end 12 of the upper 20. The foot-receivingopening 28 may provide access to the footwear cavity 24. For example,the foot-receiving opening 28 may receive a foot to secure the footwithin the footwear cavity 24 and facilitate entry and removal of thefoot from and to the footwear cavity 24. The body 26 and thefoot-receiving opening 28 may vary from what is illustrated in FIGS.1A-1B without departing from the scope of the present disclosure. Forexample, in some configurations, the body 26 may constitute lessmaterial and the foot-receiving opening 28 may be larger and/or of adifferent shape.

The tongue 30 may extend between the footwear cavity 24 and thefastening system 32. Similar to the body 26 of the upper 20, the tongue30 may consist of different materials connected together. In thisregard, the tongue 30 may be formed separately from, but attached to,the body 26 in a manner that allows a user of the article of footwear 10to modify the dimensions of the foot-receiving opening 28. For example,the user of the article of footwear 10 may manipulate the position ofthe tongue 30 to allow his or her foot to easily enter into or exit fromthe footwear cavity 24 through the foot-receiving opening 28.

The fastening system 32 may include one or more fasteners (e.g., lace36) extending along the upper 20. In some configurations, the upper 20may include apertures such as apertures 38 and/or other engagementfeatures such as fabric or mesh loops that receive the fasteners. A userof the article of footwear 10 may tighten or loosen the fastenersthrough the plurality of apertures 38 in order to tighten or loosen thebody 26 and tongue 30 of the upper 20 around the user's foot or to allowhis or her foot to enter into or exit from the footwear cavity 24. Whilethe fasteners are generally shown and described herein as the lace 36,it will be appreciated that the fasteners may include straps, cords,hook-and-loop, or any other suitable type of fastener, within the scopeof the present disclosure.

The sockliner 34 may be located within the footwear cavity 24 along aportion of the body 26 of the upper 20. In some configurations, thesockliner 34 resides in a location within the footwear cavity 24 tocontact a plantar surface of the user's foot in order to enhance thecomfort of the article of footwear 10.

While the article of footwear 10 is shown and described herein asincluding the tongue 30, the fastening system 32, and the sockliner 34,it will be appreciated that the tongue 30, the fastening system 32, andthe sockliner 34 are optional features of the article of footwear 10.Moreover, the size, shape, location, and other characteristics of eachmay vary greatly between different implementations of the article offootwear 10.

The sole structure 22 may include different layers, such as an outsole42, a midsole 40, and an insole or sockliner 34, for example. Each layermay serve a particular function. For example, the insole or sockliner 34may be designed to contact the foot and to provide enhanced comfort tothe foot, as described above. In this regard, the insole 34 may includea layer formed into the sole structure 22 such that the insole 34 isdisposed between the midsole 40 and the upper 20 in an assembledconfiguration.

The outsole 42 is generally positioned on a bottom surface of thearticle of footwear 10. In particular, the outsole 42 may include alayer coupled to the midsole 40, such that the outsole 42 contacts theground surface during normal use. In this regard, the outsole 42 mayprovide a degree of cushioning to the foot during use of the article offootwear 10. Further, the outsole 42 may be formed from anabrasive-resistant material such as rubber to protect the article offootwear 10 and provide the article of footwear 10 with the ability topositively grip the ground surface during use.

The midsole 40 may include a body 44 and one or more fluid-filledchambers 46, and may be disposed between the outsole 42 and the upper 20and/or the insole 34. In some configurations, the midsole 40 may extendbetween the heel end 12 and the forefoot end 14 along the Y-axis andbetween the lateral side 16 and the medial side 18 along the X-axis inorder to improve various performance-related characteristics of thearticle of footwear 10. For example, the midsole 40 may provide bothstability and a cushioning system for the user's foot.

The body 44 of the midsole 40 may be formed at least in part from a foampolymer material, such as polyurethane, ethylvinylacetate, or anothermaterial, and may include a cavity 47 (FIG. 3B) defined at least in partby a first (e.g., upper) chamber contact surface 86, a second (e.g.,lower) chamber contact surface 88, and a third (e.g., side orperipheral) chamber contact surface 90 (each shown, for example, inFIGS. 3B and 3C).

The fluid-filled chamber 46 may be disposed within the cavity 47 of thebody 44 and may include a first barrier layer 52, a second barrier layer54, a foam structure (e.g., layer) 60, and a tensile member 70. Thefirst barrier layer 52 may be coupled to the second barrier layer 54 ata seam 56. In some configurations, the first barrier layer 52 is sealedto the second barrier layer 54 at the seam 56 such that the first andsecond barrier layers 52, 54 collectively define an interior void 58.The interior void 58 may include one or more fluids. For example, air,nitrogen, hexafluorethane, sulfur hexafluoroide, other gases, otherfluids, or a mixture thereof, may fill the fluid-filled chamber 46. Thefirst and second barrier layers 52, 54, including the sealed seam 56therebetween, may maintain the fluid within the interior void 58 atambient pressure or, alternatively, may maintain the fluid within theinterior void 58 at a pressure that is greater than ambient pressure.The fluid-filled chamber 46, including the pressure thereof, providesimproved cushioning properties by absorbing impact forces created whenthe outsole 42 strikes the ground surface during use.

In some configurations, the fluid-filled chamber 46 may extend along theX-axis by a width W₄₆ and be substantially centered within the body 44of the midsole 40 along both the Z and X-axes. The width W₄₆ of thefluid-filled chamber 46 may extend across a majority (e.g., greater than50% and less than 100%) of the midsole 40 along the X-axis. In thisregard, it will be appreciated that the width W₄₆ of the fluid-filledchamber 46 may be greater or less than the width W₄₆ shown in FIG. 1Bwithout departing from the scope of this disclosure.

The configuration (e.g., size, position, and/or quantity) of thefluid-filled chamber 46 within the body 44 of the midsole 40 may varyfrom the position illustrated in FIGS. 1B and 2A without departing fromthe scope of this disclosure. For example, the fluid-filled chamber 46may be positioned off-center relative to the body 44 along the X, Y,and/or Z-axes. Additionally, the midsole 40 may incorporate more thanone fluid-filled chamber 46 having differing designs within the scope ofthe present disclosure. As illustrated in FIG. 2A, in someconfigurations, the fluid-filled chamber 46 includes a length L₄₆ thatspans from the heel end 12 to the forefoot end 14 along the Y-axis ofthe article of footwear 10.

As illustrated in FIG. 2B, an article of footwear 100 is provided andincludes a fluid-filled chamber 48. The article of footwear 100 and thefluid-filled chamber 48 may be substantially similar to the article offootwear 10 and the fluid filled chamber 46, respectively, except asotherwise shown or described herein. The fluid-filled chamber 48 may bedisposed within the heel end 12 of the article of footwear 100 and mayhave a length L₄₈ that spans only a portion of the distance between theheel and forefoot ends 12, 14 along the Y-axis.

As illustrated in FIG. 2C, an article of footwear 200 is provided andincludes a fluid-filled chamber 50. The article of footwear 200 and thefluid-filled chamber 50 may be substantially similar to the article offootwear 10 and the fluid filled chamber 46, respectively, except asotherwise shown or described herein. The fluid-filled chamber 50 may bedisposed within the forefoot end 14 of the article of footwear 200 andmay have a length L₅₀ that spans only a portion of the distance betweenthe heel and forefoot ends 12, 14 along the Y-axis.

As illustrated in FIG. 2D, an article of footwear 300 is provided andincludes the fluid-filled chamber 48 and the fluid-filled chamber 50.The article of footwear 300 may be substantially similar to the articleof footwear 10 except as otherwise shown or described herein. While thearticles of footwear 10, 100, 200, 300 are shown and described herein ashaving one or two fluid-filled chambers 46, 48, and/or 50, it will beappreciated that an article of footwear may include more than twofluid-filled chambers 46, 48, and/or 50 within the scope of the presentdisclosure.

The foam structure 60 may be disposed within the interior void 58 of thefluid-filled chamber 46. As illustrated in FIG. 1B, in someconfigurations, the foam structure 60 may be disposed adjacent to thesecond barrier layer 54 such that a first (e.g., lower) surface 602 ofthe foam structure 60 engages a first (e.g., upper) surface 55 of thesecond barrier layer 54 at a first attachment 96. The foam structure 60may be formed from an open-cell foam core, such as the open-cell foamcore disclosed in U.S. Pat. Nos. 4,874,640 and 5,235,715, thedisclosures of which are fully incorporated herein by reference.Alternatively, the foam structure 60 may be formed from one or moreflexible materials such as a mesh material, a nylon material,ethylene-vinyl acetate copolymer, or any other suitable material thatprovides cushioning and can be shaped into the shape of the foamstructure 60. The material of the foam structure 60 provides improvedcushioning properties by absorbing the impact forces created when theoutsole 42 strikes the ground surface during use. Utilization of highdensity foam may increase the strength of the foam structure 60 andincrease the length of time over which the impact forces are spread whenthe outsole 42 strikes the ground surface. Further, combining the foamstructure 60 with the fluid-filled chamber 46 provides the article offootwear 10 with both responsive-type cushioning due to the foamstructure 60 and soft-type cushioning due to the fluid contained withinthe chamber 46. These components advantageously can be installed in thearticle of footwear 10 at the same time once the fluid-filled chamber 46is formed.

With reference to FIG. 3C, the tensile member 70 may be disposed withinthe interior void 58 of the fluid-filled chamber 46 and may include afirst (e.g., upper) substrate 82, a second (e.g., lower) substrate 84,and a plurality of individual tensile fibers 85 extending between thefirst substrate 82 and the second substrate 84. As illustrated in FIGS.1B and 3B, in some configurations, the tensile member 70 is disposedbetween the foam structure 60 and the first barrier layer 52 relative tothe Z-axis such that (i) the first substrate 82 engages a second (e.g.,lower) surface 53 of the first barrier layer 52 at a second attachment94 and (ii) the second substrate 84 engages a second (e.g., upper)surface 601 of the foam structure 60 at a third attachment 97. The firstand second substrates 82, 84 may include a substantially planarconfiguration. Accordingly, the attachment 94 between the tensile member70 (at the first substrate 82) and the first barrier layer 52, as wellas the attachment 97 between the tensile member 70 (at the secondsubstrate 84) and the foam structure 60, may be formed in a manner suchthat substantially all of the first and second substrates 82, 84 contactthe second surface 53 of the first barrier layer 52 and the secondsurface 601 of the foam structure 60, respectively.

The plurality of individual tensile fibers 85, which may deflect easilywhen a compressive force is applied to the tensile member 70, mayinclude various sizes (e.g., diameter, length along the Z-axis),cross-sectional shapes (e.g., circular, rectangular, or other polygon),and/or materials. For example, as illustrated throughout the figures, adistance along the Z-axis between the first and second substrates 82, 84may vary such that the length of the tensile fibers 85, as measuredalong the Z-axis, may also vary from one tensile fiber 85 to anothertensile fiber 85 and/or from one configuration of the fluid-filledchamber 46 to another configuration of the fluid-filled chamber 46. Whenthe fluid-filled chamber 46 and/or the tensile member 70 is in a neutralstate (i.e., no external force is applied to the fluid-filled chamber 46and/or the tensile member 70), one or more of the plurality ofindividual tensile fibers 85 may experience a tensile force in order tomaintain a desired shape (e.g., FIG. 1B) of the fluid-filled chamber 46by preventing or inhibiting the first barrier layer 52 from moving awayfrom the second barrier layer 54 along the Z-axis.
